- A nice article at Heise on the recent break through of the chromatic number of the plane. t.co/8h6qI6SUiH (in german). The announcement of Aubrey de Grey is here: t.co/vtjMynMtWb

- Yard run this Friday morning. t.co/9Tft22qjZY Registration t.co/ckDYOPduAC Was fun last year. I hope to get up in time t.co/buQv8k64fp
- Langlands wins the Abel. To cite t.co/DM0wC8Z7D9 "The Langlands program, which is widely considered the largest project of its kind in contemporary mathematical research". Frenkel called it the GUT of MATH. It is on my bucket list, just once to understand the question.
- A nice question of Tanton. As Alon Amit suggested, b=5 could be a counter example. Here is a test up to 100000 (in mathematica). F[k_,b_]:=IntegerDigits[2^k,b]; PalindromicQ[x_]:=(x==Reverse[x]); b=5; Do[If[PalindromicQ[F[k,b]],Print[{k,b}]],{k,100000}] t.co/w2RVUHvn08
- @jamestanton I can confirm that for b=5, there are no palindromes 2^n for base b for n smaller than 100000 (of course disregarding the trivial cases n=1,2). It indeed could be difficult to prove but as larger n gets, as less likely this is going to happen as more and more conditions appear.

- Piday day Stephen Hawking died. "Theory of Everything" is a nice portrait. Three clips from that movie with math content. In the first one, a blackboard in Sciama's office with a flux integral. The other two clips show equations from general relativity. t.co/6pNKTYyCmi t.co/Iyk9qy25ih
